AP BIOLOGY

Detailed explanation-1: -Explanation: The food chain begins with the sun: plants get their energy by photosynthesizing sunlight into energy, and then herbivores eat those plants to get their energy. Carnivores who then eat the herbivores are getting that sunlight passed along from sun to plant to herbivore to carnivore.

Detailed explanation-2: -An animal that eats producers, like plants or algae, is called an herbivore. Carnivores eat other consumers. This means they eat other animals. Animals that eat both producers and consumers are called omnivores.

Detailed explanation-3: -A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.

Detailed explanation-4: -Animals get their food from plants, either directly by eating plants or indirectly by eating animals that eat plants.
